My initial thought is that since they all test the same, they are probably ok.
You can use a DVM or a scope to check for the presence of the crank sensor signals at the ignition module. But you have to have the connector hooked to the module while probing for the signals. I don't know exactly which year your car is.
The way I did mine was to remove the connector, and use wire wrap wire (this is very thin insulated 30 gauge wire) tucked in beside the pins I wanted to probe. The wire was small enough to let me plug the connector back in, with the small wires fitting in between the connector and the module.
You don't want to remove the crank sensor unless you know it is bad.
